The patch is incomplete because I wanted to only print the 
warning if the user hasn't requested the mpeg muxer and the 
muxer doesn't know if the user specified a muxer or not.

I am assuming that ac3 in MPEG-1 system stream is defined 
and that MPlayer and WMP just don't support it.
If this is not correct, the patch makes no sense imo.
